Down a group the reactivity increases. So, barium (Ba) is more reactive than strontium (Sr).
Caesium is the most reactive.
Fluorine
Ba; Barium
on the periodic table, Ba means Barium, an alkaline element, its used in many things from fire works to medicines. :) hope this helped

Caesium is the most reactive.
Cs (Caesium) is the most reactive!!!!

Barium (Ba) is the most electropositive element. In general, electropositivity (reverse of electronegativity) decreases across the rows of the periodic table and increases down the columns.
Fluorine
Atomic Number is 47; Atomic Mass is 137.3; Element Name is Barium; Classified as the Alkaline Earth Metals.
Barium is an element, with a chemical symbol of Ba. As an element it does not have a formula.
The symbol is Ba.
Ba; Barium
Those elements that are also is group II of the Periodic Table, namely Be, Mg, Sr, Ba and Ra.
Ba is the symbol of Barium element.
All metals more reactive than Zn: Al, Mg, Na, Ca, Ba, K, Li
